Security ratings
Sold Secure is the UK's independent test for locks. Ratings go from Bronze to Silver, Gold and Diamond. Many insurers require a minimum rating, often Gold, so check your policy.
Types of lock
| Type | Strengths | Downsides | Best for |
|---|---|---|---|
| D-lock (U-lock) | Strong for its weight | Limited reach | Everyday locking in town |
| Chain and padlock | Very strong, flexible reach | Heavy | Long stops, home and work storage |
| Folding lock | Packs small, decent reach | Usually lower ratings than a D-lock | Light everyday use |
| Cable lock | Light, cheap | Easy to cut | Securing wheels or saddles alongside a main lock |
How to lock up
- Lock to something solid that can't be lifted over or cut through.
- Lock the frame and rear wheel together, and secure the front wheel too if it's quick-release.
- Fill the gap inside a D-lock so there's no room for tools.
- Keep the lock off the ground so it can't be braced and hit.
- Pick a busy, well-lit spot with CCTV if you can.
Extra steps
- Register your bike with a UK bike register and note your frame number.
- Take photos of your bike and keep the receipt.
- Use two different locks for longer stops, so a thief needs two sets of tools.
FAQs
How much should I spend?
A common rule is around 10% of the bike's value.
Are smart locks worth it?
Alarms and trackers can help, but they don't replace a strong physical lock.
